Description

Buckling device of radiator

[technical field]

The utility model is about a kind of buckling device of radiator, is meant a kind of easy to assembly and can guarantee between radiator and the heat generating component buckling device of radiator in conjunction with isostasy especially.

[background technology]

Central processing unit is the nerve center of computer treatmenting information, and can the overall performance of computer promote, and depends on the performance of central processing unit to a great extent, so the release of high-frequency high-speed central processing unit just becomes inexorable trend.But, the heat that high-frequency high-speed will make this central processing unit produce is more and more, further make the computer-internal temperature more and more higher, serious prestige is being assisted the stability of central processing unit operation, for guaranteeing the normal operation of central processing unit energy, the heat that it produced must in time be discharged, for this reason, the be everlasting surface of central processing unit of industry installs heat abstractor combination additional, with the heat of timely its generation of discharge.

Existing buckling device of radiator has two kinds usually: a kind of is that radiator is placed in the storage tank with the stuck-module of its corresponding cooperation, by fastener radiator and stuck-module one are fastened on the connector that is equiped with central processing unit again, but, the overall weight of radiator all concentrates on this central processing unit in this kind fixed form, not only be difficult to pass through vibration-testing, and very easily cause the adhesion inequality, cause the surface local loose contact, thereby influence radiating effect; Another kind of radiating mode is to establish screw on foot of radiator, and on the connector of mainboard or installing central processing unit, be provided with corresponding with it screw, directly radiator is locked on mainboard or connector by screw again, but, location difficulty during this structure assembling, and because this fixed form is to be rigidly connected, cause the pressure inequality easily, cause each binding site imbalance of pressure on the radiator after the assembling, both influenced radiating effect, make circuit board produce mechanical deformation again easily.

[summary of the invention]

It is a kind of easy to assembly and can guarantee between radiator and the heat generating component buckling device of radiator in conjunction with isostasy that the purpose of this utility model is to provide.

The purpose of this utility model is achieved through the following technical solutions: the utility model buckling device of radiator comprises a backboard and plurality of fixed part, wherein each fixture comprises a head, a fixed leg, a junction surface and a spring, this spring housing is on this fixed leg, this head is located at this fixed leg upper end, this junction surface is located at this fixed leg lower end, is provided with internal thread in this junction surface; This backboard has a flat board, this flat board has upwards extended some projections, each projection upper end is provided with and the corresponding external screw thread of junction surface internal thread, and the external screw thread by each projection and the internal thread at each fixture junction surface match can be with a fastener of radiator on a motherboard.

Compared with prior art, the utility model buckling device of radiator has easy to assembly and can guarantee between radiator and the heat generating component advantage in conjunction with isostasy.

With reference to the accompanying drawings, in conjunction with the embodiments the utility model is further described.
